Pour the apricots onto a sieve, drain well and cut into cubes. Drain on kitchen paper. Cream fat, sugar, vanilla sugar and salt. Add the eggs individually, alternating with the cornflour, and stir until creamy. Stir in buttermilk, bitter almond flavour and grated lemon peel. Mix flour, except 2 tablespoons, and baking powder. Stir into the dough.
Mix remaining flour with the apricot cubes and fold in. Put the dough into a greased springform pan with breadcrumbs and a tube bottom insert (26 cm Ø) and smooth it down. Bake in the preheated oven, 2nd shelf from below (electric oven: 175 °C/ convection oven: 150 °C/ gas: level 2) for approx. 1 1/4 hours. Let the cake cool down a little in the tin, turn out of the tin and let it cool down on a cake rack. Dust with icing sugar and arrange on a cake plate. Mango crème fraîche ice cream is delicious with it
